Personal update: I've joined Anthropic. I think the next few years at the frontier of LLMs will be especially formative. I am very excited to join the team here and get back to R&D. I remain deeply passionate about education and plan to resume my work on it in time.

Dario is wrong.
He knows absolutely nothing about the effects of technological revolutions on the labor market.
Don't listen to him, Sam, Yoshua, Geoff, or me on this topic.
Listen to economists who have spent their career studying this, like @Ph_Aghion , @erikbryn , @DAcemogluMIT , @amcafee , @davidautor

Akhirnya ada 1 engineer Indo yang lagi di final round sama cofounder, super exciting! 🚀

Anak tech yang jago2 harus dapet tempat berkarya yang bagus, di Indo udah hampir gak ada, sayang banget talent banyak yang udah lahir dari era unicorn (gojek, traveloka, etc.) kalau stop sampai sini

I'm thrilled to announce the definitive course on Claude Code, created with @AnthropicAI and taught by Elie Schoppik @eschoppik. If you want to use highly agentic coding - where AI works autonomously for many minutes or longer, not just completing code snippets - this is it.

Claude Code has been a game-changer for many developers (including me!), but there's real depth to using it well. This comprehensive course covers everything from fundamentals to advanced patterns.

After this short course, you'll be able to:
- Orchestrate multiple Claude subagents to work on different parts of your codebase simultaneously
- Tag Claude in GitHub issues and have it autonomously create, review, and merge pull requests
- Transform messy Jupyter notebooks into clean, production-ready dashboards
- Use MCP tools like Playwright so Claude can see what's wrong with your UI and fix it autonomously

Whether you're new to Claude Code or already using it, you'll discover powerful capabilities that can fundamentally change how you build software.

I'm very excited about what agentic coding lets everyone now do. Please take this course!

claude code is having it's cursor moment after karpathy sensei's post. never been a better time to try it.

my latest blog on how to get the most out of claude code 2.0 and other agents in general is up now. grab a chai and have fun reading!

Agency > Intelligence

I had this intuitively wrong for decades, I think due to a pervasive cultural veneration of intelligence, various entertainment/media, obsession with IQ etc. Agency is significantly more powerful and significantly more scarce. Are you hiring for agency? Are we educating for agency? Are you acting as if you had 10X agency?

Grok explanation is ~close:

“Agency, as a personality trait, refers to an individual's capacity to take initiative, make decisions, and exert control over their actions and environment. It’s about being proactive rather than reactive—someone with high agency doesn’t just let life happen to them; they shape it. Think of it as a blend of self-efficacy, determination, and a sense of ownership over one’s path.

People with strong agency tend to set goals and pursue them with confidence, even in the face of obstacles. They’re the type to say, “I’ll figure it out,” and then actually do it. On the flip side, someone low in agency might feel more like a passenger in their own life, waiting for external forces—like luck, other people, or circumstances—to dictate what happens next.

It’s not quite the same as assertiveness or ambition, though it can overlap. Agency is quieter, more internal—it’s the belief that you *can* act, paired with the will to follow through. Psychologists often tie it to concepts like locus of control: high-agency folks lean toward an internal locus, feeling they steer their fate, while low-agency folks might lean external, seeing life as something that happens *to* them.”

Excited to release new repo: nanochat!
(it's among the most unhinged I've written).

Unlike my earlier similar repo nanoGPT which only covered pretraining, nanochat is a minimal, from scratch, full-stack training/inference pipeline of a simple ChatGPT clone in a single, dependency-minimal codebase. You boot up a cloud GPU box, run a single script and in as little as 4 hours later you can talk to your own LLM in a ChatGPT-like web UI.

It weighs ~8,000 lines of imo quite clean code to:

- Train the tokenizer using a new Rust implementation
- Pretrain a Transformer LLM on FineWeb, evaluate CORE score across a number of metrics
- Midtrain on user-assistant conversations from SmolTalk, multiple choice questions, tool use.
- SFT, evaluate the chat model on world knowledge multiple choice (ARC-E/C, MMLU), math (GSM8K), code (HumanEval)
- RL the model optionally on GSM8K with "GRPO"
- Efficient inference the model in an Engine with KV cache, simple prefill/decode, tool use (Python interpreter in a lightweight sandbox), talk to it over CLI or ChatGPT-like WebUI.
- Write a single markdown report card, summarizing and gamifying the whole thing.

Even for as low as ~$100 in cost (~4 hours on an 8XH100 node), you can train a little ChatGPT clone that you can kind of talk to, and which can write stories/poems, answer simple questions. About ~12 hours surpasses GPT-2 CORE metric. As you further scale up towards ~$1000 (~41.6 hours of training), it quickly becomes a lot more coherent and can solve simple math/code problems and take multiple choice tests. E.g. a depth 30 model trained for 24 hours (this is about equal to FLOPs of GPT-3 Small 125M and 1/1000th of GPT-3) gets into 40s on MMLU and 70s on ARC-Easy, 20s on GSM8K, etc.

My goal is to get the full "strong baseline" stack into one cohesive, minimal, readable, hackable, maximally forkable repo. nanochat will be the capstone project of LLM101n (which is still being developed). I think it also has potential to grow into a research harness, or a benchmark, similar to nanoGPT before it. It is by no means finished, tuned or optimized (actually I think there's likely quite a bit of low-hanging fruit), but I think it's at a place where the overall skeleton is ok enough that it can go up on GitHub where all the parts of it can be improved.

Link to repo and a detailed walkthrough of the nanochat speedrun is in the reply.

[Andrej Karpathy @karpathy]

How to become expert at thing:
1 iteratively take on concrete projects and accomplish them depth wise, learning “on demand” (ie don’t learn bottom up breadth wise)
2 teach/summarize everything you learn in your own words
3 only compare yourself to younger you, never to others

🤯🤯BREAKING: temuan wartawan dibalik dalang penjarahan. 🤯🤯

Kesaksian oleh "paid actor" yg ketinggalan rombongan bernama Ahu:

-4 mobil konvoy berangkat bareng dari cimahi, terus lanjut jemput orang di bandung, bandung barat, sukabumi, cianjur sampai bogor rombongan 600 motor.

-Mampir ke tanggerang dulu, kamis nyampe senayan lemparin molotov.

-Sebelum berangkat, diperintshkan membuat dulu bom molotov. “Ada 160 botol dibuat,” isinya minyak tanah.

-Botol itu kemudian diangkut ke kendaraan minibus putih. “Macam Alphard tapi bukan, saya lupa namanya,” kayaknya hiace ya?

-Di DPR ketemu rombongan lain yang direkrut dengan cara yang sama dari daerah jawa & bekasi.

-Sebagian kelompok beraksi di DPR, rekan-rekan Ahu yang lain membakari halte-halte Transjakarta.
“Itu pakai molotov yang dibuat di kampung,”

-Sebagian dari anggota rombongan, kata dia, ditugaskan mengunggah siaran live di TikTok.

-Dapet brief penjarahan ke 4 rumah, Pimpinan rombongan memberi tahu ada empat rumah yang bakal dijarah dan lokasinya mulai dari priuk. tapi ga berangkat karena kepencar dari rombongan.

-Saat diperlihatkan video penjarahan sama wartawan Ahu mendaku mengenali sebagian penjarah. “Itu yang baju biru juga rombongan saya, Bang”

Provokator demo di Jakarta pada Jumat 29 Agustus 2025 ditangkap personel polisi yang sedang mengawal aksi.

Provokator berbaju hijau dan celana panjang abu-abu tersebut ternyata anggota Badan Intelijen Strategis (Bais) TNI.

Berdasarkan kartu anggota yang dibawa, provokator demo tersebut bernama Sudi Suwarno.

Sudi Suwarno berpangkat Mayor Infanteri dengan nomor NRP 21960328960875.

Provokator tersebut menjabat sebagai Komandan Tim 2 Den IV Satuan Intel Bais TNI.

Dalam kartu anggota tersebut juga dijelaskan Sudi diizinkan membawa pistol sebagai persenjataan saat bertugas.

Senjata yang digunakan berjenis Sig Sauer P224 Sas produksi Jerman kaliber 9 mm.

Kartu anggota yang dibawa provokator tersebut masih berlaku hingga 31 Desember 2025.

Berdasarkan informasi yang didapat https://t.co/K7igDpu1ha, Sudi Suwarno ditangkap polisi di Pejompongan, Jakarta, Jumat (29/8/2025) malam.

Kira-kira, apa tujuan provokator tersebut? Dan permainan apa dibalik keterlibatan TNI saat demo beberapa terakhir?
